+## Known Issues
+
+CP/M (and workalike) OSes have significant restrictions on filename
+characters.  The FAT application will block any attempt to create a
+file on the CP/M filesystem containing any of these prohibited
+characters:
+
+|         `< > . , ; : = ? * [ ] _ % | ( ) / \`
+
+The operation will be aborted with "`Error: Invalid Path Name`" if such
+a filename character is encountered.
+
+Since MS-DOS does allow some of these characters, you can have
+issues when copying files from MS-DOS to CP/M if the MS-DOS filenames
+use these characters.  Unfortunately, FAT is not yet smart enough to
+substitute illegal characters with legal ones.  So, you will need to
+clean the filenames before trying to copy them to CP/M.
+
+The FAT application does try to detect the scenario where you are
+copying a file to itself.  However, this detection is not perfect and
+can corrupt a file if it occurs.  Be careful to avoid this.

+# WDATE
+
+`wdate` is a utility for CP/M systems that have Wayne Warthen's
+ROMWBW firmware. It reads or sets the real-time clock, using function
+calls in the BIOS. It should work on any RTC device that is supported by
+ROMWBW, including the internal interrupt-driven timer that is is available
+on some systems. 
+
+`wdate` differs from the `rtc.com` utility that is provided with the
+ROMWBW version of CP/M in that it only gets and sets the date/time. 
+`rtc.com` can also manipulate the nonvolatile RAM in certain clock
+devices, and modify the charge controller. However, `wdate` is (I would
+argue) easier to use, as it takes its input from the command line, which
+can be edited, and it's less fussy about the format. It doesn't require
+the date to be set if you only want to change the time, for example.
+ In addition, `wdate` has at least some error checking.
+
+`wdate` displays the day-of-week and month as English text, not 
+numbers. It calculates the day-of-week from the year, month, and day.
+RTC chips usually store a day-of-week value, but it's useless in this
+application for two reasons: first, the BIOS does not expose it. Second,
+there is no universally-accepted way to interpret it (which day does
+the week start on? Is '0' a valid day of the week?)
+
+## Syntax
+
+| `WDATE`
+| `WDATE ` *`<hr> <min>`*
+| `WDATE ` *`<hr> <min> <sec>`*
+| `WDATE ` *`<year> <month> <day> <hr> <min> <sec>`*

+two-digit year starts at 2000. 
+
+    A> wdate /?
+
+Show a summary of the command-line usage.
+
+## Notes
+
+I've tested this utility with the DS1302 clock board designed by Ed 
+Brindly, and on the interrupt-driven timer built into my Z180 board. 
+However, it does not interact with hardware, only BIOS; I would expect 
+it to work with other hardware.
+
+wdate checks for the non-existence of ROMWBW, and also for failing 
+operations on the RTC. It will display the terse "No RTC" message in 
+both cases.
+
+The ROMWBW functions that manipulate the date and time operate on BCD 
+numbers, as RTC chips themselves usually do. wdate works in decimal, so 
+that it can check that the user input makes sense. A substantial part of
+the program's code is taken up by number format conversion and range 
+checking.
+
+## Etymology
+
+The `WDATE` application was written and contributed by Kevin Boone.

+
+This function performs a device dependent reset operation on the DSKY.
+The display will be cleared, keyboard queue will be flushed, and
+chip will be reinitialized.  The returned Status (A) is a standard

+buffer utilization is not available, the function may return simply 0 or
+1 where 0 means there is no character available and 1 means there is at
+least one character available.
+
+The value returned in register A is used as both a Status (A) code and

+  handles the specified character unit. Values are listed at the start
+  of this section. Device Number (E) indicates the physical device
+  number assigned per driver which is always 0 for DSKY.
+
+  Device Mode (H) is used to indicate the variant of the chip or circuit 
+  that is used by the specified unit. The Device I/O Base Address (L) 
+  indicates the starting port address of the hardware interface that is 
+  servicing the specified unit. Both of these values are considered 
+  driver specific. Refer to the associated hardware driver for the

+;   RCBUS Z80 COLECOVISION-COMPATIBLE CONFIGURATION FOR J.B. LANGSTON'S GAME BOARDS
+;==================================================================================================
+;
+; THIS CONFIGURATION ENABLES DRIVERS FOR THE TMS9918 AND SN76489 BOARDS BY J.B. LANGSTON
+; AND THE YM2149 BOARD BY ED BRINDLEY. THE TMS9918 IS CONFIGURED TO USE THE COLECOVISION
+; PORTS AND HAS INTERRUPTS DISABLED BECAUSE COLECOVISION USES NMI, WHICH WOULD BREAK CP/M
+; WHEN ENABLED. IT IS CONFIGURED FOR A 3.686MHZ CPU CLOCK IN ORDER TO BE COMPATIBLE WITH
+; COLECOVISION GAMES. THE FIRST SIO PORT IS CONFIGURED TO RUN AT 115200 BPS WITH THE CPU
+; RUNNING AT THIS SPEED. THE SECOND SIO PORT IS CONFIGURED TO RUN AT 115200 BPS WITH THE
+; SECOND CLOCK SET TO 7.373MHZ. LOWER BAUD RATES CAN BE ACHIEVED ON THE SECOND PORT BY
+; MOVING THE SECONDARY CLOCK DIVIDER JUMPER (E.G., 38400 @ 2.458MHZ). THE BAUD RATE DOES
+; NOT NEED TO BE CHANGED IN THIS CONFIGURATION FILE IN ORDER TO DO THIS, BUT THE DEVICE
+; LIST WILL INCORRECTLY SHOW THE PORT RUNNING AT 115200 REGARDLESS OF THE CLOCK DIVIDER.
+; UNCOMMENT THE LINE THAT SETS BOOTCON TO 1 TO BOOT ON THE SECOND SIO PORT BY DEFAULT.
+;
+; THE COMPLETE SET OF DEFAULT CONFIGURATION SETTINGS FOR THIS PLATFORM ARE FOUND IN THE
+; CFG_<PLT>.ASM INCLUDED FILE WHICH IS FOUND IN THE PARENT DIRECTORY.  THIS FILE CONTAINS
+; COMMON CONFIGURATION SETTINGS THAT OVERRIDE THE DEFAULTS.  IT IS INTENDED THAT YOU MAKE
+; YOUR CUSTOMIZATIONS IN THIS FILE AND JUST INHERIT ALL OTHER SETTINGS FROM THE DEFAULTS.
+; EVEN BETTER, YOU CAN MAKE A COPY OF THIS FILE WITH A NAME LIKE <PLT>_XXX.ASM AND SPECIFY
+; YOUR FILE IN THE BUILD PROCESS.
+;
+; N.B., SINCE THE SETTINGS BELOW ARE REDEFINING VALUES ALREADY SET IN THE INCLUDED FILE,
+; TASM INSISTS THAT YOU USE THE .SET OPERATOR AND NOT THE .EQU OPERATOR BELOW. ATTEMPTING
+; TO REDEFINE A VALUE WITH .EQU BELOW WILL CAUSE TASM ERRORS!
+;
+; PLEASE REFER TO THE CUSTOM BUILD INSTRUCTIONS (README.TXT) IN THE SOURCE DIRECTORY (TWO
+; DIRECTORIES ABOVE THIS ONE).

+; THE COMPLETE SET OF DEFAULT CONFIGURATION SETTINGS FOR THIS PLATFORM ARE FOUND IN THE
+; CFG_<PLT>.ASM INCLUDED FILE WHICH IS FOUND IN THE PARENT DIRECTORY.  THIS FILE CONTAINS
+; COMMON CONFIGURATION SETTINGS THAT OVERRIDE THE DEFAULTS.  IT IS INTENDED THAT YOU MAKE
+; YOUR CUSTOMIZATIONS IN THIS FILE AND JUST INHERIT ALL OTHER SETTINGS FROM THE DEFAULTS.
+; EVEN BETTER, YOU CAN MAKE A COPY OF THIS FILE WITH A NAME LIKE <PLT>_XXX.ASM AND SPECIFY
+; YOUR FILE IN THE BUILD PROCESS.
+;
+; THE SETTINGS BELOW ARE THE SETTINGS THAT ARE MOST COMMONLY MODIFIED FOR THIS PLATFORM.
+; MANY OF THEM ARE EQUAL TO THE SETTINGS IN THE INCLUDED FILE, SO THEY DON'T REALLY DO
+; ANYTHING AS IS.  THEY ARE LISTED HERE TO MAKE IT EASY FOR YOU TO ADJUST THE MOST COMMON
+; SETTINGS.
+;
+; N.B., SINCE THE SETTINGS BELOW ARE REDEFINING VALUES ALREADY SET IN THE INCLUDED FILE,
+; TASM INSISTS THAT YOU USE THE .SET OPERATOR AND NOT THE .EQU OPERATOR BELOW. ATTEMPTING
+; TO REDEFINE A VALUE WITH .EQU BELOW WILL CAUSE TASM ERRORS!
+;
+; PLEASE REFER TO THE CUSTOM BUILD INSTRUCTIONS (README.TXT) IN THE SOURCE DIRECTORY (TWO
